Getting really close to purchasing and I'm kinda on the fence between dmarcian, dmarcly, and easy dmarc. However, I'm open to pretty much anything with realistic pricing if you have alternatives to recommend.

I assume all 3 of these would get the job done, as they all seem to support dashboards, alerts, and forensic reporting. I'm curious about email volume limits though, I don't see as crystal clear picture of pricing when it comes to that - does anyone have first hand experience they'd be willing to share?

• email volume just crept up over 100k monthly in May/June
